SPECIFICATION forming part of Letters Patent No. 708,421, dated September 2, 1902.

Application filed January 22,1902- Serial No. 90,816- (N'o model.)

STEARNS, a face in a plane at right angles to the outer citizen of the United States, residing at Eldo-. surface of the sleeve 5, and at its inner terrado,in the county of Butler and State of Kanminal said member also has a circumferential sas, have invented new and useful Improverib 7 to closely abut against the guard-flange ments in Vehicle-Hubs, of which the follow-. 8 of the axle, the said inner end of the meming is a specification. her 4, including the rib 7, being equal in di- This invention relatestoavehicle-hub; and ameter to the guard-flange 8, so that the surthe primary object of the same is to improve faces of the rib and flange will be flush when the construction of metallic hubs for carriage the member 4 is properly applied over the and otherwheels and provide them with means spindle 2. The hub also includes a member for holding the inner ends of the spokes more 9, having a radial flange 10, with an inner securely, and each is composed of detachable straight face adapted to be disposed parallel parts which will enable the hub to be conwith the outer face of the flange 6 of the memveniently secured to the axle at the inner end her 4. The member 9 is tubular and has an of said hub, the parts of which the hub is comouter rounded closed terminal 11, and in asposed being adjustable at any time to tighten sembling the two members the member 9 is the inner ends of the spokes, and thereby proslipped over the sleeve 5 of the member 4. duce a more durable wheel.

After the hub is applied on the spindle structed witha spiral groove 3, extending lon- 2 it is obvious that it must be secured to pregitudinally thereof from the outer to the invent accidental movement or disengagement, ner terminals. On the spindle 2 is removably and for this purpose an annular clamp 15 is fitted a member 4, having a projecting sleeve provided and comprises two sections 16 and 5 formed integral therewith, the bore of the 17, connected by a hinge-joint 18, of which sleeve alining or continuing from that in the an arm 19, having its rear extremity secured member 4, and when the latter is applied the to the axle 1, serves as a pintle. The said outer end of the sleeve 5 coincides with the arm 19 stands outwardly far enough away outer end of the spindle. The member 4 also from the ad jaccnt side of the axle to compon- 10o sate for the projection of the sections 16 and 17. The clamp 15 is of box-like form and has a groove therein of such dimensions as to snugly receive the rib 7 and guard-flange 8, as clearly shown by Fig. 2, and to secure the two sections 16 and 17 the one is formed with a fulcrum-lug 20, from which is movably swung a stirrup 21, the said lug and stirrup being located adjacent to the joint of the two sections at one side and the stirrup adapted to be pushed over an outstanding lug 22, carried by the section 17. To prevent the stirrup from becoming accidentally disengaged from the lug, it is provided with a set-screw 23, which is adjusted to bind firmly against the lug 22, and thus securely hold the two sections 16 and 17 united around the rib 7 and flange 8 and maintain the hub in operative position to the spindle without liability of said hub working oft or becoming loose. The sections 16 and 17 are semicircular in contour, and by opening the same the hub can be easily withdrawn from the spindle. Though the annular flange 15 snugly engages the rib 7 and guard-flange 8, the said rib is permitted to rotate within the clamp.

To oil the part of the hub engaged by the clamp 15, the latter is formed with an oil-vent 24, which is normally closed by a vent-screw 25, and when the hub is applied to the spindle 2 oil or other suitable lubricant is placed within the hub in sufficient quantity to fill the chamber 14, and from the said chamber the oil or lubricant is conveyed through the groove 3 around the spindle with obvious ad vantages.

The improved hub is absolutely dust-proof and will prevent Wear on the spindle. It is also simple in construction and comparatively inexpensive in the cost of manufacture. It will also be seen that the arm 19 holds the annular clamp 15 in connection with the axle, so that the said clampis always in position for engagement with the inner terminal of the hub when the latter is applied.

Having thus described the invention, what is claimed as new is- 1. A hub comprising separable members, one of which has an outwardly-projecting sleeve with a smooth outer surface and the other an outwardly-projecting tube with a smooth bore to frictionally fit over said sleeve, the tube having an outer integral closed eX- tremity which is normally located in advance of the outer end of the sleeve to form an oilreceptacle, the two members also having opposing radially-projecting flanges which are spaced apart to receive wheel-spokes, and means for securing said flanges.

2. A hub comprising separable members, one of which has an outwardly-projecting sleeve with a smooth outer surface and the other an outwardly-projecting tube with a smooth bore to frictionally fit over said sleeve, the tube having an outer integral closed extremity which is normally located in advance of the outer end of the sleeve to form an oilreceptacle, the two members also having opposing radially-projecting flanges which are spaced apart to receive wheel-spokes, means for securing said flanges combined with an axle-spindle to fit in the sleeve, said spindle having a spiral groove therearound which eX- tends full length of the spindle and communicates with said outer receptacle.

3. A hub having an outer closed portion combined with an axle having a spindle on which said hub is removably fitted, and an annular clamp comprising hinged sections, one of the sections carrying a pivoted locking-stirrup with a set-screw therein, and the other a lug for engagement by said stirrup and screw.

In testimony whereof I affix my signature in presence of two witnesses.
